Definition of the noun reactance

What does reactance mean as a name of something?

noun - plural: reactances

  1. opposition to the flow of electric current resulting from inductance and capacitance (rather than resistance)

Alternative definition of the noun reactance


  1. [physics, electrics] The opposition to the change in flow of current in an alternating current circuit, due to inductance and capacitance; the imaginary part of the impedance.
  2. [psychology] An emotional reaction in direct contradiction to rules or regulations that threaten or eliminate specific behavioral freedoms.

  1. Reactance is a motivational reaction to offers, persons, rules, or regulations that threaten or eliminate specific behavioral freedoms. Reactance occurs when a person feels that someone or something is taking away his or her choices or limiting the range of alternatives.
  2. Reactance a.k.a. Electrical reactance: In electrical and electronic systems, reactance is the opposition of a circuit element to a change of electric current or voltage, due to that element's inductance or capacitance. A built-up electric field resists the change of voltage on the element, while a magnetic field resists the change of current. The notion of reactance is similar to electrical resistance, but they differ in several respects.
